And it can effectively provide a multimedia service based on this.

1 is a block diagram of a multimedia content service system according to a preferred embodiment of the present invention. In general, a user terminal 110, a network 120, a content server system 130, and a content archive 140 may be described. ).

Referring to FIG. 1, the user terminal 110 may be a wired terminal (for example, a computer having a network connection means, etc.) or a wireless terminal (cellular phone, PCS, PDA, IMT-2000, PDA phone, smart phone, etc.). And a service application processing block 112, a multimedia middleware block 114, and a platform block 116, wherein the content server system 130 includes a metadata transmission / reception block 131 and a content service management block 132. ), The metadata parsing block 133, the service configuration information generation block 134, the content retrieval block 135, and the content transmission block 136.

First, the service application processing block 112 in the user terminal 110 is a multimedia application program layer. When a user requests a service of a specific multimedia content, the service application processing block 112 generates information such as characteristic information of the terminal, middleware configuration characteristics, and state, It stores the request multimedia content (eg, the identifier information of the requested multimedia content) in the form of service request metadata, and calls the application programming interface (API) provided by the multimedia middleware block 114 to call the network ( 120 to transmit to the content server system 130, and when the multimedia content requested by the user is received from the content server system 130, the application process consumes (plays or saves to the storage medium) through application processing. do. In addition, the service application processing block 112 provides a function of making a data processing request, a resource use request, and the like required for the multimedia middleware block 114 when the application is executed, and outputting the result (display, audio output), and the like. , Receiving response metadata from the content server system 130, delivering the response metadata to the multimedia middleware block 114, receiving configuration information from the multimedia middleware block 114, and delivering the configuration information to the content server system 130. do. Here, the network 120 may be a wired network including the Internet or a wired or wireless network including a mobile communication network and the Internet.

Next, the multimedia middleware block 114 is a software platform for general purpose multimedia processing that is independent of hardware and applications. The multimedia middleware block 114 acquires and installs a service module necessary for executing a multimedia application, thereby providing data necessary for the application. Process and provide the result to the service application processing block 112, that is, parse the response metadata to download (obtain) the required service module and install it in the multimedia middleware, and the installation result and the multimedia configuration status information (i.e., the installed service). Module list) to the service application processing block 112, and the service modules that are no longer needed for the execution of the application are used in the unused state and the resources of the multimedia middleware are optimally managed. And, the application does Software middleware that provides functions such as calling and executing resources of the underlying platform block 116 and delivering the result to the service application processing block 112.

In addition, the multimedia middleware block 114 downloads and installs necessary service modules through parsing response metadata and installs them in the multimedia middleware, and then generates a ready message indicating completion of installation of the required service module to generate a service application processing block. And as a result, the service application processing block 112 transmits the ready message to the content server system 130 via the network 120. At this time, the ready message is also a kind of metadata.

Here, the multimedia middleware block 114 may include, as an example, a service manager 1141, a service loader 1143, and a plurality of components 1145 /. 1-1145 / n) (or a service group).

Referring to FIG. 2, the service manager 1141 and the service preparer 1143 each perform a function of registering or preparing a new multimedia middleware service component required for multimedia content consumption. Here, the service manager 1141 also manages the life cycle of the multimedia middleware components and services, such as updating or discarding necessary multimedia middleware components and services.

In addition, the service request metadata may be composed of text data expressed using an extensible markup language (XML) or binary data transformed into a binary file.

In addition, the user terminal 110 provides the multimedia content service request from the content server system 130 to the multimedia content service request of the multimedia middleware service components and response metadata including the middleware service component configuration information for processing thereof. The multimedia middleware service components required to parse the received response metadata are registered with the middleware system to construct the multimedia middleware service components.

That is, since the response metadata is in a markup language such as XML, the response metadata has a tree structure. The user terminal 110 reads an XML metadata file to represent data in all tree structures and searches the tree in an application program. The middleware component is configured through a series of processes to read the necessary data from the node. More specifically, the multimedia middleware block 114 parses the response metadata to find out which service module is needed and from the location of the service module. The necessary service module is downloaded and in-built into the middleware to create an environment for executing a multimedia application program to be provided from the content server system.

The component configuration information, which is the multimedia middleware configuration information of the user terminal, includes a component identification number, a component name, a component information descriptor, a component creator, a component license information, an available component interface, a service, a service implementation, a usage environment, and a component.

In addition, similar to the service request metadata, the response metadata may be composed of text data expressed using an extended markup language (XML) or binary data transformed into a binary file.

In addition, a middleware component may have a service, which is a processing unit for simple information processing as a multimedia information function block that can be used (called) in an application program and has an application program interface, or a more complicated function. It may also include a service having a recursive structure that can have child services therein to perform the operation.

Furthermore, a service is a functional block capable of processing multimedia information, which is composed of unit functional blocks for executing simple functions, or as an example, as shown in FIG. 3, a layer for performing complex functions. In general, it can be composed of a composite function block composed of several child services.

Meanwhile, the metadata transmission / reception block 131 in the content server system 130 inversely converts the request multimedia content transmitted through the network 120 and the service request metadata including middleware configuration information of the user terminal into the original signal before transmission. (Demodulation) transfers to the content service management block 132, and when the response metadata of the middleware component configuration information and service configuration information for processing thereof is provided from the component configuration information generation block 134, Alternatively, a function of converting (modulating) a signal that can be transmitted wirelessly and transmitting the same to the user terminal 110 through the network 120 is performed.

In addition, when the metadata transmission / reception block 131 receives a ready message indicating that preparation for processing of the requested multimedia content is completed from the user terminal 110, the metadata transmission / reception block 131 demodulates it to the content service management block 132. To pass.

Next, the content service management block 132 performs analysis management of service request metadata received from the user terminal, generation and management of response metadata corresponding thereto, and withdrawal management of multimedia content requested for service from the user terminal. The service request metadata received from the metadata transmission / reception block 131 is transmitted to the metadata parsing block 133 for analysis, and the analysis result provided from the metadata parsing block 133 is analyzed. And manages generation of response metadata corresponding to the service request metadata.

That is, the metadata parsing block 133 parses and analyzes the service request metadata and transmits the analysis result to the content service management block 132, and the service configuration information generation block 134 is the content service management block 132. Based on the analysis result received from the user, the user can smoothly consume the multimedia content requested by the service, that is, response metadata composed of multimedia middleware service components and middleware service component configuration information for processing thereof is generated. The generated response metadata is transmitted to the metadata transmission / reception block 131 for transmission to the user terminal 110. To this end, the service configuration information generation block 134 stores lists of service modules required for successfully executing the multimedia middleware service.

In addition, the content service management block 132 generates a content retrieval message including delimiter information of the requested multimedia content in response to the preparation completion message transmitted from the metadata transmission / reception block 131. 131).

In response, the content retrieval block 135 retrieves the corresponding multimedia content from the content archive 140 based on the received content retrieval message, and delivers the retrieved multimedia content to the content transmission block 136. Here, the content archive 140 is a storage medium that stores various types of multimedia contents to serve to an unspecified number of users.

Subsequently, the content transmission block 136 converts (modulates) the multimedia content data received from the content retrieval block 135 into a signal capable of being wired and / or wirelessly, and converts the multimedia content data through the network 120. To transmit to a remote user terminal (110).

That is, the multimedia service system of the present invention generates service request metadata including user terminal characteristics and multimedia middleware configuration information when a specific multimedia service is requested from any user terminal, and transmits the service request metadata to the content server system. Receives response metadata of multimedia middleware service components and middleware service component configuration information for processing thereof from the system, and configures the multimedia middleware service and the multimedia middleware service component to provide the multimedia service to one's own terminal. By downloading and installing in multimedia middleware), various multimedia content services can be provided at any time through various kinds of multimedia middleware terminals having different middleware structures. You can receive services.

In this case, when the user terminal first requests a multimedia content service by accessing the content server system, service request metadata including request multimedia content, user terminal characteristics, and middleware configuration information is generated and transmitted to the content server system. When requesting other multimedia content while the connection session is maintained, the service request metadata is not generated and transmitted to the content server system.

In addition, the multimedia service system of the present invention can be applied to various application fields for the multimedia middleware service by defining and dividing a profile of the user terminal multimedia middleware according to the multimedia service application domain and specializing it for a specific application domain.

Next, a process of serving multimedia content to a user terminal through transmission and reception of service request metadata and response metadata according to the present invention using a multimedia service system having the above-described configuration will be described.
